In this study, the effect of microwaves along with chlorine ions on the leaching of sulfide concentrate of the Sungun copper complex has been investigated. To this end, a 10% by weight pulp solution before being utilized in the leaching process has been conditioned in a Bosch household appliances grade microwave oven with a frequency of 2450 MHz with different amounts of power. Microwave radiation causes more solvents to come into contact with the concentrate, increasing the mass transfer rate and reducing the time required for the process. In this research, the role and effect of microwaves in improving the acidic leaching of copper sulfide minerals have been investigated. The goal was to increase copper recovery and reduce the time required for the leaching process. The results indicate that the recovery of dissolved copper without sodium chloride and microwave irradiation was about 15.42%, with the addition of sodium chloride it has increased to 43.51%, and with microwave irradiation, it was increased by 15% which was equal to 58.63% [1-4].
